rlhe bearing member 211 is formed with a flange 26 overlying the casing 17 and secured thereto in any suitable manner as'by machine screws 2 7.

n use, the shaft Y15 is connected in any Ysuitable manner to a motor as an internal combustion engine, and in operation, -the member 11 is rotated about the axle by the shaft 15 and during the rotation thereof-.thc

. gear 18 is caused to wobble or move about rection preliminary to being movedv into mesh with the. gear during the next phase of the wobble. Y Y y This transmitting mechanism is particuandis entirely located in the axle casing, and further in that'a large number of teeth are'in mesh or in clutch at all times, thus allowing small gears for strength and Ya What I claimV is:

1. A driving axle construction comprising an axle, a gear connected to the axle and arranged Vconcentric therewith, a rocking having its axis extending diametri cally crosswise of the axis of the axle, a gear encircling the axle and meshing with the to the axis of said support, and means for rocking the latter gear about its transverse axis, saidmeans beingmounted upon the axle, substantially as and for the purpose 5 described.

2k. A driving axle construction f comprisand the ring 23with bearingsY ing an axle,a gear arranged concentric with the axle and connected'thereto,a casing env closing the axle, a frame mounted the casing and surroundingthe axle and being pivoted to the casing on an axis extending diametrically relatively to the axis ot' the axle, a gear comprising a ring encircling the axle and meshing with said gear and being pivoted to the frame on a transverse axis extending crosswise of the axis 'of the toV axleand-at a right angle lto the axis of the traine, and means withinthe casing and con'-v Vnected to the latter gearv to` movethefsame about saidgframe, substantially as and-"for the'purpvose specified. Y. g Y Y 3. A .lriving axle construction comprising an axle, a gear arranged concentricfwith the axle and connectedthereto, afcasing Ven-l closingthe'axle, a ramefmoun'ted Vonthe casing and surrounding'tlie'faxle andvbeing.,

pivoted to the casing on .an axis extending' diametrically relatively to theV axis of the axle, a gear comprising a Vring encircling the axle and meshing with-said gear and being pivoted to the iframe on a transverse axis extending Acrosswise of the axis of the axle and at a right angle to the axis of the vframe,

and meanswithin the casing and ,connected Y to said gear ringto move the same about its transverse axis and about `.the axis of said frame, said means being mounted cuand-VV rotatable about the axle Vand having cam means arranged about the axis of `the axleV and eccentric thereto and `coa'cting with the latter gear ring, substantially vas and forl the purpose set forth. Y Y

f1.' A driving axle'constructioncomprising two sections, dierential gearing connecting the sections and including a drivinggear, a casing, Vdrivingineans including` a member rlocated in the casing and mounted on one of the sectionsv and rotatable about the same, and means fortransm'itting motion from the driving member to said, driving gear,^said ,means comprising a wobble" gear supported in the casing and meshingY with said driving" gear, the wobble gear encirclingthe axis of the axle and having ahub'connected ,eccenl trically tothe driving member, substantially as and for the vpurposespeciiied.V
